Great conversation and many great topics broached. Lex did a great job. The insights on what impact we are really having is sobering and weirdly encouraging given the damage a looming Republican Congress might seem like it could inflict. Probably less than we imagine. I think the big gap in the conversation and a gaping hole in the economic perspective Lomburg takes is the impact our actions have on the natural environment. While I think the point he made around time to improvement from fracking is fair, the fact that all of his cost benefit examples relate to the benefit to humans and ignores the billions of other living organisms on the planet that will also suffer consequences from global warming potentially including annihilation ignores value beyond calculation. If we just think about humans I think we will realise the doom he says is overstated . A planet without a flourishing natural environment will not be worth living on. We all need to bring that value to the fore and I know my children certainly feel that way . I don’t have confidence that the worlds technologists are going to be our saviours. After all, how much has been invested in cryptocurrencies and how positive is that. Personally I think we all need to question the ecological footprint we leave and we know some people have a far bigger footprint than others. Classic tragedy of the commons. And they mostly don't care. They are stealing our children’s future . Case in point : Elon Musk asking developers to fly to San Francisco for a code review for Christ's sake. Reducing consumption has to be a big part of the answer in a finite world.

I agree with your point. I have appreciated the whole conversation, particularly Andy's layered considerations and multiple perspectives on complex issues, however it was very anthropocentric and never considered and discussed properly the loss of biodiversity, and the risks for wildlife which could ultimately lead to breaks in the food supply chains. Lomborg even said at some point that we have lost all of these animal and fish stocks because nobody really cared about them so far, so I would have wanted to know if in his opinion it was time to start properly caring and increase the conservation efforts or that may not provide enough returns on the dollar invested.

Yes, hard to believe that in four hours we didn't really get into this reality - that human affairs are a subset of global ecosystems and, by heavily interfering with that system, we're doing ourselves and other species a grave disservice. I've explored this with Herman Daly, the pioneer in ecological economics, and others. Still haven't gotten that posted here but you can watch a wonderful video here: https://www.youtube.com/watch?v=khgIHOmEGxs Thanks for this helpful input!

Transatomic is no longer a going concern - since a few years ago. Your position on nuclear while not nearly the worst I've seen is pretty bad- there is no nuclear waste problem, there never has been... when you moved to your new place in Maine did you ask the real estate agent if the place had working waste management system, shower drain, garbage disposal? Probably not- you just assumed that. Now why don't you assume that the folks that designed nuclear power plants thought about waste management?

The nuclear fuel cycle is pretty simple: plants get fuel assemblies shipped in by truck on a regular basis (weekly), they inspect it very closely by hand, then every 18 months or so they put the fuel assemblies in the reactor, where they get hot for 3 years give or take- so here's where it gets slightly more complicated: that fuel is very radioactive now and mist be shielded - water is a perfect shield! So they take the top off the reactor and set that aside - at this point the fuel in the reactor is covered by what water is above it in the reactor vessel an you are looking at hot dangerous fuel - but perfectly safe with plenty of water between you and it. So how do they get the fuel up and out of the reactor? They flood the whole space 32 feet above the lip of the reactor- there is a channel or tube from the reactor containment to the long term cooling pool. The fuel assemblies are either carried upright through the deep channel, or laid down and rolled through a tube- to the cooling pool ( a deep water filled thick concrete holding tank- FOR 10 YEARS. Just sitting there under water- harmless (yes they circulate the water, no it's not a huge deal if those pumps go down) We've been dry cask storing spent fuel since the mid 80s- never been and incident of any kind. No one is interested in spent nuclear fuel. And globally we generate about 2500tons a year- care to guess how much coal ash we make? (hint we have over 1,500,000,000 tons of coal ash in North America alone. There is enough UF6 stacked up in Paducah KT to generate all of US electricity for 1000 years-- give or take. Carbon free. We can get uranium out of seawater. That stuff is everywhere. There are places in Canada where every other rock you trip over is mostly uranium...

After the fuel assemblies have cooled there for a decade - they go into dry casks outside where they take up valuable parking spaces until such time as someone wants to reprocess that fuel into new fuel of burn it in a fast reactor. At this point we don't reprocess fuel because it would be many times more expensive than just burning new fuel- nuclear fuel is cheap (about a 1/5 of what running a gas plant costs) (a gas plant might burn 20% of its capital cost per year... (a $2B plant- just estimating $500,000,000 in fuel costs alone- same in nuclear $75,000,000)

Your statement that wind and solar are growing was it explosively? is absurd- wind and solar don't keep up with increased demand, are grossly unreliable, expensive and hideously slow to deploy- oh I can hear it now "nuclear takes too long" - also just not true when compared to RE - sure gas is 1/4 the build time- and cheaper (money is such a poor metric when it comes to life on Earth though- but hey that's just me) Long term straight up accounting - 15 years down the road nukes are cash cows.

But we all know there is no straight up accounting when it come to nuclear (everything costs twice as much because of strangulating regulators that kill nuclear with fees (to wit a large portion of the $1.1B grant PG&E is getting to keep Diablo Canyon up and running will go straight back into the NRC- hundreds of millions of dollars in paper work which will amount to more than the cost of fueling that same plant. That is absurd.

No one ever mentions Price-Anderson. There's billions just sitting there.

Sorry to be so blunt Andrew but you need to, we need you to, up your game here and stand up for nuclear.

Emissions first, peace and justice will follow.

Will they though?

You write well, but I think the second problem won’t be solved by nuclear power.

Then, as the Ukraine situation demonstrates, it makes dangerous situations worse. Even Lombard wasn’t as positive about nuclear as you seem to be.

If you want to say what makes you so confident in your final lines I’d be curious to know. It does not seem obvious to me in any way .

I appreciate the post though.

Jake are you responding to me? What second problem are you referring to? The situation in Ukraine is just war- the reactors are shut down and are much less likely to cause problems... pretty hard to blow up a containment and a reactor. I be into a discussion if Andrew would participate... the discourse re nuclear is weak and poorly thought out. I hate that.

Yes, I do need to host a fresh discussion of nuclear energy in the context of #PutinsWar and more.

Hi Tim,

Yes I was (new to substack and this comment function).

I respect your in depth knowledge of nuclear. I basically anti, but I’m not an idiot! That discussion is one of the most important ones out there.

Basically I was responding to the end of your post:

“ Emissions first, peace and justice will follow.”

I think this was a good way to end the post because it is the bottom line of where this discussion needs to go.

I was very seriously asking about the presuppositions that go into the above statement ie that peace and justice will follow once emissions are dealt with.

You are clearly more expert than me in nuclear tech but I work in mediation and conflict resilience so my eye is very much on the realistic possibility of said peace and justice .

I am wondering where your certainty comes from that peace and justice will follow. If I had that confidence I can imagine agreeing nuclear is the best option. I’m not a fundamentalist on this issue.

Nuclear waste is one sticking point , war is the second.

If I could see the emergence of the level of conflict resolution processes and conflict literacy at the local and international levels then I think nuclear would win the day.

What I see is the opposite.

If I was wanting to win the nuclear issue then what I would do is accept that in a world with lower risk of military aggression nuclear wins hands down. The greater the risk of military aggression the less good an idea it seems at a gut level ( which I think is the important level in this kind of debate).

We live in a world of MAD mutually assured destruction . The ‘pro nuclear for eco reasons’ camp , I think , would be well advised to take the strongest possible anti war stance possible.

If even a fraction , a minuscule fraction, of the cost of that infrastructure was invested in the cutting edge social technology of conflict resolution ( not to mention a fraction of the the military budget!) and it’s “r&d” then we could say that as a society we are actually taking the second part of the equation seriously.

Humans have such immense technological power. It is our moral , ethical and social development , essentially our wisdom to use that power that is lagging so desperately behind.

There is an accelerationist tendency in our culture to put the foot to the floor and try to use tech to solve every problem. The risk that humans pose each other, the planet is not one that I think tech can solve. (Actually AI is by the level headed estimates potentially a worse risk than climate by at least some experts.)

These things can’t in reality be easily parsed.

The questions around how to reduce existential risk need to be platformed in a way than enables real engagement ie democratic engagement .

Conflict hinders even the discussions from happening, it is pushing internal democratic process into retrograde. Polarisation is increasing.

These are not good signs . I do not see peace and justice flowing out from using nuclear to try and deal with emissions.

I don’t think the real ecological problem itself even gets dealt with .

So , arguably , it fails on the core issue of human relationship with earth systems and can only increase the risk of human to human threat.

I hope me voicing this is useful. I have a minus 10 desire to be in some kind of debate about facts where we attempt to convince each other.

What I am open for is attempting to understand the different dimensions of the issue(s).

Hope that makes sense .

All the best

Jake

Your conversation with Lomborg, moderated by Lex Fridman, was fascinating. I particularly appreciated your advice to young people. I've been able to watch 1/3rd of it so far. My major criticism is that I thought you and Lomborg downplayed the worst case climate change scenario, which I understand to be the risk of triggering multiple tipping points at ~1.5 deg C of global warming and given that risk the need for urgent actions to restrain global warming to 1.5 deg C or as close to that as possible, per the precautionary principle.

Thanks Jim. I've dug in for a long time on the tipping points question (2009, e.g. https://www.nytimes.com/2009/03/29/weekinreview/29revkin.html). Almost inevitably I find the same answer from top scientists. There is still deep uncertainty about truly nonlinear outcomes, and that is the reason to work as hard as we all can to cut emissions, boost resilience in the meantime, particularly where vulnerability is greatest (https://revkin.substack.com/p/behind-global-climate-emergency-rhetoric-21-08-06) and intensify scientific and innovative capacities to have the awareness and agility to ramp up responses. It's important to understand, though, that 1.5C and 2C were politically-negotiated thresholds, not scientific lines in the sand. If you read the recent Science tipping points paper carefully, it's clear the list of nine are still putative more than imminent. I'm overdue to host a Sustain What tipping points conversation with a batch of folks. https://www.science.org/doi/10.1126/science.abn7950 Your note spurs me to make that a higher priority. Thanks again.

I want Curry, Mann and Hansen in the same room. Open discussion. That’s the starting points for all of this: science. Not opinions from pop economists or policy wonks.

I'm not a policy wonk, if that's who you're referring to. I'm a journalist who's covered every facet of climate change since the mid 1980s - from the basic science through the social sciences, including digging in on the work of all of the scientists you mention. I agree that climate science lays the geophysical foundation, and there's much there that's still deeply uncertain (as Judith rightly points out). But the prime debates right now are still far more on how to interpret and act on that science. It'd be great if Lex had the bandwidth to do a series of climate converstions but that's just not realistic. For what it's worth, I'd be happy to host a conversation with Curry, Hansen and Mann. It'd quickly become apparent that the main differences are over interpretations of the science and preferences for solutions. Hansen is all about nuclear and an unrealistic carbon fee. Mann has laid out strong political preferences. Curry is more interested in questions than prescriptions. Here's a piece on Curry: https://archive.nytimes.com/dotearth.blogs.nytimes.com/2009/11/27/a-climate-scientist-on-climate-skeptics/ Here's some of my coverage of Mann: https://www.nytimes.com/search?dropmab=false&query=michael%20mann%20hockey%20stick%20climate%20revkin%20andrew&sort=best I've been writing about Hansen's work since his Senate testimony in 1988: http://j.mp/warming88revkin I've also covered Hansen's tendency to hyperbole when trying to press for policy action: https://www.nytimes.com/2009/03/29/weekinreview/29revkin.html

I'm new to substack as well- but i am not new to nuclear or the debate thereof- or LACK of debate. Sick to death of it. Emissions are the defining issue of our time, ignore that at our own peril. The issue is that there is no debate for me. I simply cannot reason with someone that believes without evidence- ie that nuclear waste is dangerous, that any radiation causes cancer, that radiation is this that and something else... it is not. It's not a mystery, unlikely that you or anyone else will ever come in contact with harmful doses is -- well only greater than zero. If I say zero someone (who doesn't get it obviously) will call me on. Like your chances of getting covid off a french fry... only greater than zero. As far as conflict dispute- here re nuclear for me that's like debating on the existence of the number 7.

You have conflated nuclear energy with weapons of war (nuclear weapons are just weapons the fact that they are nuclear means bigger boom for less weight- much less weight. The nuclear fallout is not trivial but compared to the explosion, no not relevant) Peaceful nuclear has little to do with weapons. Don't forget that. Done with this issue. (if you have questions glad to answer, but at some point I will insist that you stipulate to the facts... so that we can all move on from that forever)

Nuclear waste dominates the issue. In real life - nuclear fuel is boring. (Andrew has a picture of me with a fuel assembly mock up- I can't post it. I love that stuff! Talk about all day...

Nuclear waste is not and has not been a problem, and likely never will be. Every nuclear power plant has systems designed for the handling of spent nuclear fuel AND plenty of space to store ALL the spent nuclear fuel it will burn in its lifetime (say 80 years) (we can and do move spent nuclear fuel after 20-30 years cooling and it can be reprocessed into new fuel... but that costs money and time. It's much cheaper, easier and cleaner to burn new fuel- but the real story is how much of it there is: 2500 tons per year globally. All 450 reactors or so only make 2500 tons of what you call "nuclear waste".

No one has ever been killed or even seriously hurt handling SNF.

Contrast the with 750,000,000 tons of coal ash waste per year globally. The digits tell the story.

2,500

750,000,000

How many zeros for the CO2? The digits tell the story.

Since the 80s when we started dry cask storage of spent nuclear fuel (not waste!) - not one incident, not one.

And just like that, I'm done with the nuclear waste issue* (questions sure, go ahead, glad to... prepare to stipulate)

Will peace and justice follow? Well my friend we are weaponizing both nuclear and gas even as we speak.

Unrelated I'll note that Zoporizhia is a $14B asset and isn't blown up yet but that Nordstream gas pipeline is.

Pretty hard to destroy a nuclear power plant. Making a big ugly mess on the other hand is pretty darn easy. Destroying new fuel is pointless. Destroying used fuel would be hmmm dunno how hard that would be? Guessing it's under at least 30 feet of water (maybe more) and not really easy to get out of those pools even with a big bomb (missile? would suck) but you're still only faced with a big ugly hard to clean up local (certainly not regional) mess. Doubtful anyone would be killed by radiation. Explosions kill people. Radiation not so much (ie Hiroshima and Nagasaki - very few killed by the radiation mostly by fire and the explosion. Done with Putin and nuclear power plant wars. That guy is evil, don't conflate clean safe reliable nuclear energy into his war. Way more people will die without nuclear energy there now. Nuclear saves lives.

Cancer rates have gone all over the world. 40M dose of nuclear medical isotopes come straight out of a reactor every year. Nuclear medicine saves lives. Done.

Natural gas and the Haber-Bosch process have saved more people from suffering and misery than any other technology. Vaccines are second. It would take 200 large reactors to replace steam reforming for fertilizer the fertilizer we need globally. People die from lack of fertilizer.

Nuclear powered desalination will change the world- massive desal makes nuclear look small cheap and easy. Nuclear could feed the world. Overnight we need 20,000 reactors.

Andrew?

Both agree in Anthropogenic Global Warming, but neither ventures to say how much is man induced.

The earth has warmed and cooled 5 or 6 times during the Holocene without fossil fuels or extensive farming. A scientific mind would try to understand what caused these other warming and cooling periods before declaring a climate crisis with a scientific basis. CO2, N2O and CH4 all have limited affects and water vapor is the major GHG.

Andy, have you looked at the competing model for how an atmosphere warms a planet by Nikolov and Zeller? If you haven't already you should watch PhD Physical Scientist Ned Nikolov's presentation before deciding between the Greenhouse model and the Nikolov-Zeller model. You can watch his video "Demystifying" on his YouTube channel "Truth & Insights". Thanks, and enjoy! https://youtu.be/gnt9YZyCTAQ

Hi andrew,

this interview was the first time I’ve consciously come across your work.

My question I was left with was from early on. I was thinking how can this guy (you) not challenge the idea of fracking being a good idea?

I see the promotion of fracking as a symptom of the very carbon fundamentalism I think you oppose.

If the problem at a deeper level is that there is inadequate understanding of ecology (and climate) then surely it’s obvious that the destructive processes of fracking are at a deeper level counter productive . Seeming quick fixes that don’t deliver.

Would you like to comment on that?

Basically it left me wanting to ascertain if you are a credible source of information for me. I otherwise appreciated your perspective.

This was a glaring opportunity to open up just how reductionist thinking leads to industrial strategy co-opting ecological concern for short term gain at long term expense .

Did you duck it for a reason ? Or are you in support of fracking? That’s what I’d like to know!

Another question that I have had regarding CO2... what is the desired level of CO2 in the atmosphere, and how do we determine that level How do we measure the key target CO2 levels?.. point in time... average over some period? How does that target level of CO2 compare to historical estimates?

Hi Andy, hope your Thanksgiving day was a good one!

First will point out that I am an environmentalist who has real concerns about various ways that societies are affecting the environment.. my biggest concern relates to the ocean and pollution particularly. Would love to see a massive effort along the lines of the Ocean Cleanup project. I have donated substantially to that effort and would encourage everybody to go deep on it. Polluters should be held to account but we shouldn't delay one minute to fix that clear and present problem.

The most fundamental "climate change" question that I have relates to the chart that has been presented at different occasions over the past 20+ years showing historical temperatures plotted with CO2. I have seem many versions of the chart and they do certainly seem to show correlation. But correlation and causation are very different things.

In what I understand to be the most accurate versions of the chart, changes to temperature appear to preceed CO2 changes by many years.

Obviously, changes to CO2 would need to preceed corresponding changes to temperatures for there to be the claimed cause and effect.

This seems to have been raised my many over the years but never directly refuted. Please advise.

Thanks!
